Human African trypanosomiasis, endemic to sub-Saharan Africa, is invariably fatal if untreated. Its causative agent is the
protozoan parasite Trypanosoma brucei. Eflornithine is used as a first line treatment for human African trypanosomiasis, but
there is a risk that resistance could thwart its use, even when used in combination therapy with nifurtimox. Eflornithine
resistant trypanosomes were selected in vitro and subjected to biochemical and genetic analysis. The resistance phenotype
